On the first Monday of every month, the popular Milky Way Lounge and Lanes in Jamaica Plain turns into a lively nightspot for experimental film and video, much of it locally made. This venue for emerging filmmakers to show their work is the brainchild of Evonne Hyla Wetzner, who founded the Underground Film Revolution five years ago. The program has bounced around among several locations since 1997, but settled comfortably into the Milky Way in October.

Wetzner bills tomorrow night's eclectic mix of narrative shorts as ''East Coast vs. West Coast: An Indie Rumble''; it features nine short films and videos made by artists from Massachusetts and California. Included is the premiere of local filmmaker and musician Steven Lawrence, whose ''Ted and Sage'' was shot in JP.

Other locally made shorts include Marc Landers 's ''One Eye Closed''; Chris Bentley 's ''Sonny''; Kevin Anderton 's commentary on the local housing crunch, ''First, Last and Security''; Mikki Krimmel 's ''Mason Dixon''; and ''Hairdo,'' a documentary by Cambridge residents John Capron, Jonathan Sahula, and Caroline Toth that follows students at a local beauty school to New York City for a hairstyling competition (the film screened at the Coolidge Corner Theatre's Director's Cut Series early last year). Wetzner has high praise for Californian Anna Biller 's 16mm horror/Western/musical ''A Visit From the Incubus,'' Ted Mills 's short comedy ''Walk Cycle,'' and Ken Brisbois 's ''The Van Nuys Project,'' about three men and their search to discover where porn stars hang out when they're not working.

The Milky Way is at 403-405 Centre St. in JP, downstairs from Bella Luna restaurant. Screenings run from 9 p.m. to midnight the first Monday of every month (though because of Labor Day, the UFR's September screening will be held on the 9th.) Admission is $5; events are 21-plus.
